Meet the Carmex Threading Tap, Spiral Point UNC Supercut Tap—a precision tapping solution built for professionals who need reliable UNC threading in demanding materials. Designed for high-speed machining, this tap combines toughness and accuracy to keep production moving.

• Thread size / type: 1/4" diameter, 20 TPI UNC (Unified National Coarse) for standard coarse-thread applications
• Pattern: Spiral Point (gun-style) geometry that aggressively starts threads and facilitates efficient chip evacuation
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during tough tapping operations
• Design: UNC Supercut geometry engineered for durable cutting action and long tool life in challenging materials
• Chip control: Spiral point directs chips away from the cutting edge, reducing clogging and improving thread consistency
• Application suitability: Ideal for production and repair work where reliable UNC threading and fast cycle times are essential

The Carmex UNC Supercut tap is built to deliver precise, clean threads while standing up to the heat and wear of high-speed tapping. The cobalt-infused HSS-E composition provides lasting rigidity and edge retention, helping you achieve consistent results across tough materials. With its spiral point geometry, this tap reduces chatter and promotes smooth engagement, enabling accurate threading with fewer reworks. Whether you’re fabricating components or repairing assemblies, this tap offers dependable performance in standard UNC coarse-thread applications.
